Handle DW_OP_GNU_implicit_pointer in dwarf assembler
DW_OP_GNU_implicit_pointer refers to a DIE with an offset of different
sizes in different dwarf versions. In v2, the size is the pointer size,
while in v3 and above, it is the ref_addr size. This patch fixes
dwarf assembler to emit the correct size of offset. We've already fixed
this size issue in gdb,
